A camera includes: a ring-like body mount having an inside diameter smaller than about 48 millimeters; and a solid-state image pickup device arranged oppositely to the body mount, the solid-state image pickup device having a rectangle light receiving section with a diagonal line length of about 43 millimeters or more. An apparent shape of the solid-state image pickup device viewed from a front surface side of the body mount is a rectangle in which one or more corners are oblique.
Legal claims defining the scope of protection, as filed with the USPTO.
1. An interchangeable lens being attachable to a camera body, the interchangeable lens comprising: a ring-like lens mount being attachable to a ring-like body mount of the camera body having an inside diameter, wherein the ring-like lens mount is configured to engage with a corresponding one or more of a plurality of body-side latches of the ring-like body mount; an optical system configured to form a subject image being pick up by a solid-state image pickup device arranged opposite to the ring-like body mount, the solid-state image pickup device having a rectangular light receiving section with a specific diagonal line length, wherein in a perspective from a lens attached side of the ring-like body mount, an apparent shape of the solid-state image pickup device is a rectangle having one or more oblique corners; wherein the interchangeable lens is configured to electrically connect to a plurality of body-side contact pins located around the solid-state image pick up device and between the ring-like body mount and the solid-state image pick up device.
2. The interchangeable lens according to claim 1 , wherein a diameter of the ring-like lens mount is smaller than the inside diameter of the ring-like body mount.
3. The interchangeable lens according to claim 1 , wherein the diameter of the ring-like lens mount is approximately 40 millimeters.
4. The interchangeable lens according to claim 1 , wherein the ring-like lens mount is made of a metal.
5. The interchangeable lens according to claim 1 , further comprising an adapter configured to attach the interchangeable lens to the camera body.
6. The interchangeable lens according to claim 5 , wherein the solid-state image pickup device is at least a 35 millimeter full-frame solid-state image pickup device.
7. The interchangeable lens according to claim 1 , wherein the rectangular light receiving section is in the shape of a rectangle having a long side of about 36 millimeters and a short side of about 24 millimeters.
8. The interchangeable lens according to claim 1 , wherein the apparent shape of the solid-state image pickup device is a rectangle having four oblique corners.
9. The interchangeable lens according to claim 1 , wherein the plurality of body-side latches are projected in an inner circumference of the ring-like body mount, and wherein, in a perspective from the lens attached side of the body mount, at least one corner of the solid-state image pickup device is hidden by at least one of the plurality of body-side latches.
10. The interchangeable lens according to claim 1 , further comprising a holding member configured to hold the ring-like body mount and the solid-state image pickup device, wherein the holding member has an opening opposite to the solid-state image pickup device, and wherein the apparent shape of the solid-state image pickup device is defined by the opening.
11. The interchangeable lens according to claim 10 , wherein the opening is located outside of the rectangular light receiving section.
12. The interchangeable lens according to claim 10 , wherein the holding member further includes a hollow cylinder-like frame that is configured to attach to the ring-like body mount, and a contact pin holder being provided in part or all of an internal wall surface of the hollow cylinder-like frame.
13. The interchangeable lens according to claim 12 , wherein the internal wall surface of the contact pin holder is tilted to allow an inside diameter to become wider as a location of the internal wall surface of the contact pin holder becomes closer to the solid-state image pickup device at least in one of the one or more oblique corners of the apparent shape of the solid-state image pickup device.
14. The interchangeable lens according to claim 12 , wherein the holding member further includes a mask that is configured to block unnecessary light between the contact pin holder and the solid-state image pickup device.
15. The interchangeable lens according to claim 1 , wherein the solid-state image pickup device is a full-frame pickup device.
16. The interchangeable lens according to claim 1 , wherein the solid-state image pickup device is at least a 35 millimeter full-frame solid-state image pickup device.
